Container



Patented May 16, 1939 CONTAINER Isaac n Wilcox, Fulton, N. Y., assignor to 08- wego Falls Corporation, Fulton, N. Y., a corporation of New York Application February 28, 1936, Serial No. 66,259 7 Claims. (01. 229-14) This invention relates to containers of the type fabricated from cardboard or heavy weight paper stock and used to package merchandise, such as food products for retail.

More particularly the invention has to do with a container suitable for packaging merchandise for retail trade, the container being so constructed that it is liquid tight and may be readily filled, and may be conveniently emptied. Such containers are used extensively in connection with the retail of ice-cream, and it is necessary that the container be liquid tight. To render these paper containers liquid tight, it has been common practise to coat the container with a 15 moisture proof' substance, such as paramn.

This method is unsatisfactory in that it increases the cost of the container without efiecting a permanent liquid tight receptacle. It is dilficult to flow the paraifin to all parts of the container. Where the container is used for seasonal goods, such as ice-cream, it is necessary to manufacture large quantities of the containers in advance and store them for use during the active season. During storage, if the containers are subjected to summer temperatures, the

paraflin becomes softened, and in some instances this renders the container leaky. The paraflin coated container is also unsatisfactory in that because the ice-cream is solid when packed into ,the container, it is necessary to use a spoon, or

like implement, to remove the contents from the container.

The present invention has, as an object, a container of the type referred to so constructed that it is and remains liquid tight under all circumstances, and which structure does not add to the cost of parafiin coated .containers now in use.

The invention has, as a further object, a container of such structure that the contents can be conveniently and readily removed from the container without the use of spoons, or like implements.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like 50 characters designate corresponding parts in all the views.

Figure 1 is a side elevational view, partly in section, showing a container embodying the invention.

55 Figure 2 is an exploded view of the various elements or parts of the containers involving the invention previous to assembling.

The invention comprises generally a cylindrical container including a body of fibrous material provided with an end or bottom closure, a bag of 5 thin flexible material arranged in the body of the container with the open end of the bag extending over the upper edge of the container body and overlapping the outer surface of the body adjacent the upper end thereof, a thin flexii0 ble ring encircling the overlap portion of the bag and holding it in snug engagement with the upper wall of the container body and a slip cover having a depending annular flange encircling the overlap portion of the bag with the lower edge 15 of the flange abutting against the upper edge of said ring.

The container comprises a body It! which is here shown as of conventional circular form and is slightly tapered inwardly toward the bottom. 20 The upper porton ll of the body is formed straight or cylindrical. A bottom closure l2 is secured in the lower end of the body ill in any suitable manner, as by crimping at I3. A bag l4 formed of thin flexible material, such as Cel- 5 lophane or moisture proof paper, is arranged in the body ill with the open end of the bag overlapping the upper edge |5 of the body l0 and extending downwardly around the upper portion ll of the body in overlapping relation thereto. 30 This overlapping portion l6 of the bag I4 is of appreciable length, that is, on a pint container, the overlapping portion I Bis approximately or inch in length. A ring ll of fibrous or paper material encircles the lower part of the 5 overlapping portion I 6 and is of such diameter, relatively to the diameter of the body ID, as to clamp or press the overlapping portion l6 of the bag into tight engagement with the outer surface of the container. 40

Preferably, an adhesive is applied to the'inner surface of the ring ll, as at l8, and through the application of heat, the ring I! is cemented or sealed to the overlap portion I6 of the bag.

The ring I! functions to hold the bag in the 45 container and in proper relationship thereto until the contents is placed in the container.

The container is provided with a suitable top closure, here shown in the nature of a slip cover, comprising a discoidal portion l9 which is provided with, or to which is secured, a depending annular flange 20. The internal diameter of the flange 20 is such that it also encircles the overlapping portion l6 of the bag and is preferably of such length, or depth, as to seat or abut against 5| the top edge of the ring H. The bottom edge of the flange may be provided with a slight flare or enlargement as at 2| to permit the slip cover to be more conveniently applied to the top of the container, and the cover is also preferably lined with moisture proof material, such as Cellophane" or oiled paper, and which is secured to the cover in any suitable manner, as by adhesive.

Preferably, the bag M is formed from a large disk of sheet material and is simultaneously inserted in the container body. The method and apparatus for forming and inserting the bag comprises a separate invention. When the bag is formed from the disk and inserted in the container, the side wallsof the bag assume a pleat formation, indicated as at 22. The upper or open end of the bag is folded over the upper edge of the container and about the periphery of the same, and the ring I! is pressed downwardly and sealed to the lower part of the overlapping portion It.

It will be observed that the container herein described is economical from the standpoint of manufacture, but of such structure that the liner bag is properly held in place during storage and shipment until the contents is placed in the container.

To remove the contents from the container, it is only necessary to remove the slip cover, break the ring 11 with the finger nail, invert the container over a dish, whereupon the bag with the contents slides out of the container, particularly if the latter is tapered, as disclosed in the drawing. The end of the bag is then grasped on each side by the fingers and pulled radially outwardly. Because of the pleated side wall formation of the bag, it assumes an approximate disk formation leaving the contents on the dish, or other recep tacle. It is not necessary to scoop the contents out, but the contents as a whole is readily removed from the container and may then be divided into portions according to the desires of the purchaser.
